我县有温州蜜柑3000hm~2,270多万株,每年因柑桔疮痂病损失产量200多万kg。疮痂病已成为本地温州蜜柑的主要病害之一。据分析,以往防治效果不好的原因是没有根据气象情况灵活喷施农药。由于春季降雨日数多,温湿度极适宜疮痂病病菌繁殖侵染,正确掌握喷药时间、次数、方法等尤为重要。 My county has Wenzhou Satsuma 3000hm ~ more than 2,270 million strains of citrus scab causes annual losses of more than 200 million kg. The scab has become one of the major diseases of local Satsuma. According to the analysis, the reason for the poor control effect in the past was that pesticide spraying was not conducted flexibly according to the weather conditions. Due to the large number of rainfall days in spring, the temperature and humidity are very suitable for the proliferation and spread of the disease. It is especially important to know the spraying time, times and methods correctly.
